| Background: Palikur Amerindians live in the eastern part of French Guiana which is undergoing deep-seated changes due to the geographical and economic opening of the region. So far, Palikur's traditional ecological knowledge is poorly documented, apart from medicinal plants. The aim of this study was to document ethnobotanical practices related to traditional construction in the region. Methods: A combination of qualitative and quantitative methods was used. Thirty-nine Palikur men were interviewed in three localities (Saint-Georges de l'Oyapock, Regina and Trois-Paletuviers) between December 2013 and July 2014. Twenty-four inventories of wood species used in traditional buildings were conducted in the villages, as well as ethnobotanical walks in the... |

| Sandy lobe deposits on submarine fans are sensitive recorders of the types of sediment gravity flows supplied to a basin and are economically important as hydrocarbon reservoirs. This study investigates the causes of variability in 20 lobes in small late Pleistocene submarine fans off East Corsica. These lobes were imaged using ultra-high resolution boomer seismic profiles (< 1 m vertical resolution) and sediment type was ground truthed using piston cores published in previous studies. Repeated crossings of the same depositional bodies were used to measure spatial changes in their dimensions and architecture. Most lobes increase abruptly down-slope to a peak thickness of 8 to 42 m, beyond which they show a progressive, typically more gradual, decrease... |

| Chordae tendineae architecture and their junction with papillary muscle were studied with scanning electron microscopy, comparing human and swine hearts. Papillary muscles with the corresponding chordae tendineae were obtained from human and pig (Sus scrofa) hearts after exposition of the left ventricle cavity, fixed with 4% formaldehyde. The specimens were sectioned in small samples and divided in four groups, a control one and the others submitted to digestion in a solution of 2.5% sodium hypochlorite in saline solution during 5, 10 and 15 minutes respectively. The specimens were washed and fixed in 1% osmium tetroxide in cacodylate buffer, kept in 1% tannic acid for 30 minutes, dehydrated and critical point dried, mounted and sputtered with gold. The... |

| Various studies show that agricultural cooperatives behave differently than their investor-owned counterparts. One explanation may be that the internal decision making process differs in these two governance structures. A model is developed to explore how endogenous screening rules affect efficient organizational choices and industrial structures. It is shown that screening level choice may outweigh architecture choice and that screening rules are strategic substitutes. Conditions are derived under which cooperatives are efficient organizational forms. It is also shown that competition may increase the attractiveness of investor-owned firms and circumstances are determined in which cooperatives and investor owned firms coexist in equilibrium. |

| We evaluated the ontogeny of the understory shrub Psychotria tenuinervis Müll.Arg., considering morphological and morphometric characters. Four ontogenetic stages were identified: seedling, juvenile, immature and adult (vegetative and reproductive phases). Size measurements and allometric relationships of the stem and crown were compared between the immature and adult stages. Diameter and total height of the stem, as well as crown depth and width, increased throughout the ontogenetic stages and differed among immature, vegetative adult and reproductive adult individuals. The number of branches was lower in immature individuals than in vegetative and reproductive adult individuals but did not differ between the last two. The bifurcation ratio did not vary... |

| We used a computerized approach to measure spatial complexity for the structural habitat provided by eight aquatic plant species collected from backwater lagoons located in the Upper Paraná River floodplain, Brazil. The plant species were: Cabomba furcata Schult. and Schult.f., Eichhornia azurea (Sw.) Kunth (stems and roots), Eichhornia crassipes (Mart.) Solms, Egeria najas Planchon, Heteranthera cf. zosterifolia, Potamogeton cf pusillus, Utricularia foliosa L., and Nymphaea amazonum Mart. and Zucc. The upper 0.5 m length of the terminal stems was quantified for complexity. Mean frequency and length of the interstices were significantly different among plant species. Spatial complexity varied (F = 17.30; p < 0.0001) among the different plant species... |
